Feature freeze looks like its going to be 18th (See earlier in this list
for vote). Seems like enough time to get both changes in.

Stack tells me that code freeze for 0.16 is either late this week or early
next. So no refactoring yet.

---------------------------------------
If this won't be fixed until 0.17, which is months away,
should we apply my HStore refactor patch in the meantime?
[hbase] restructure how HBase lays out files in the file system
---------------------------------------------------------------
Key: HADOOP-2478
URL:
https://issues.apache.org/jira/browse/HADOOP-2478
Project: Hadoop
Issue Type: Improvement
Components: contrib/hbase
Affects Versions: 0.17.0
Reporter: Jim Kellerman
Assignee: Jim Kellerman
Fix For: 0.17.0
Attachments: patch.txt
Currently HBase has a pretty flat directory structure. For example:
{code}
/hbase/hregion_70236052/info
/hbase/hregion_70236052/info/info/4328260619704027575
/hbase/hregion_70236052/info/mapfiles/4328260619704027575
/hbase/hregion_70236052/info/mapfiles/4328260619704027575/data
/hbase/hregion_70236052/info/mapfiles/4328260619704027575/index
{code}
All the region directories are under the root directory,
and with encoded region names, it is impossible to determine
what table a region belongs to. This should be restructured to:
{code}
/root-directory/table-name/encoded-region-name/column-family/{info,map
files}
{code}
It will be necessary to provide a migration script from
current trunk to the new structure.
